| 摘 要： | 针对长方形禁飞区下,近距离交会对接过程提出任意初始状态下轨迹安全的判断方法.先分析CW方程描述下相对运动轨迹的性质,通过分析轨迹与禁飞区最可能相交的特征点的分析和轨迹越过禁飞区相交问题的判断,判断轨迹是否安全.仿真结果表明所提出的安全判断方法能准确给出轨迹是否安全的结论,且算法简单、计算量小.

| Abstract: | An approach for estimating the safety of trajectories with arbitrary initial relative states for rectangular keep-out-zone during the rendezvous phase is proposed in this paper.The relative motions are described by CW equations,based on which the problem of safety estimation is analyzed.Then,the extremum characteristic points and their properties are analyzed,and the judgment of the intersection problem is also presented.Simulation results show that the proposed method is simple and effective in getting the... |
